I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection. Charles Darwin
Evolution is not a force but a process; not a cause but a law. John Morley
We are the product of 4.5 billion years of fortuitous, slow biological evolution. There is no reason to think that the evolutionary process has stopped. Man is a transitional animal. He is not the climax of creation. Carl Sagan
If we are going to teach creation science as an alternative to evolution, then we should also teach the stork theory as an alternative to biological reproduction. Judith Hayes
Creationist critics often charge that evolution cannot be tested, and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense. Stephen Jay Gould
Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker. Richard Dawkins
